Description Jaak Ristioja 2016-05-20 16:17:41 UTC 
This seems to be a regression after upgrading from kde-misc/yakuake-2.9.9-r3 to kde-misc/yakuake-3.0.2 together with the upgrade from KDE4 to KF5.

Reproducible: Always

Steps to Reproduce:
1. Open two KDE sessions with yakuake
2. Run mplayer somemusicfile.mp3
3. Switch to another VT using Ctrl+Alt+F1, for example.
4. Wait ~45s

Actual Results:  
The application wanting to write something to stdout blocks:

  gdb:
    #0  0x0000688bef0b3610 in __write_nocancel () at ../sysdeps/unix/syscall-template.S:84
  strace:
    write(1, "A: 245.1 (04:05.1) of 346.8 (05:"..., 48
  # ls /proc/`pidof mplayer`/fd/1 -lhd
    lrwx------ 1 myser mygroup 64 mai   20 19:13 /proc/4550/fd/1 -> /dev/pts/4

Expected Results:  
Process does not block.

Comment 1 Jaak Ristioja 2016-05-20 16:31:25 UTC 
More information:
* Only happens when Yakuake is left visible (i.e. "dropped down") when leaving the VT.
* Switching back to the VT with Yakuake immediately resumes the blocked process, even if VT is locked.
* Bug does not occur when process is launched in Konsole instead of Yakuake.
Comment 2 Jaak Ristioja 2016-05-20 16:40:12 UTC 
I think the ~45s period might be mplayer specific. Probably some OS buffer gets full because the other end (Yakuake) is not reading.
Comment 3 Andrew Crouthamel 2018-11-01 13:45:47 UTC 
Dear Bug Submitter,

This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond.

Thank you for helping us make KDE software even better for everyone!
Comment 4 Bug Janitor Service 2018-11-16 11:41:54 UTC 
Dear Bug Submitter,

This bug has been in NEEDSINFO status with no change for at least
15 days. Please provide the requested information as soon as
possible and set the bug status as REPORTED. Due to regular bug
tracker maintenance, if the bug is still in NEEDSINFO status with
no change in 30 days the bug will be closed as RESOLVED > WORKSFORME
due to lack of needed information.

For more information about our bug triaging procedures please read the
wiki located here:
https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging

If you have already provided the requested information, please
mark the bug as REPORTED so that the KDE team knows that the bug is
ready to be confirmed.

Thank you for helping us make KDE software even better for everyone!
Comment 5 Jaak Ristioja 2018-11-16 13:21:39 UTC 
It seems that this is not yakuake-specific after all. Now even other GUI processes hang when left in inactive VT.
Comment 6 Justin Zobel 2020-12-03 02:30:25 UTC 
Thank you for the report, Jaak.

As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved.

I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved" when you respond, thank you.
Comment 7 Jaak Ristioja 2020-12-03 19:11:20 UTC 
This still occurs.
Comment 8 Hector Martin 2022-10-31 07:26:33 UTC 
This also affects Konsole. Switching to another VT hangs processes that are producing output, even if Konsole is minimized or the active tab is not the one producing output.
Comment 9 Christoph Cullmann 2024-12-08 18:27:33 UTC 
Please retry this with a Qt6 based version, thanks!
Comment 10 Jaak Ristioja 2024-12-16 19:54:25 UTC 
(In reply to Christoph Cullmann from comment #9)
> Please retry this with a Qt6 based version, thanks!

I was not able to reproduce this with Yakuake 24.08.3.
Comment 11 Bug Janitor Service 2024-12-31 03:47:21 UTC 
🐛🧹 ⚠️ This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information, then set the bug status to REPORTED. If there is no change for at least 30 days, it will be automatically closed as RESOLVED WORKSFORME.
